Frayed Knights: Taking On An Army

Posted by Rampant Coyote on August 9, 2012

So here’s something with the development of Frayed Knights 2 that I haven’t come to a conclusion on yet: Changing (or tweaking)  some of the fundamentals of  combat.

When I began work on Frayed Knights, I had a lot of big ideas about designing role-playing games. A lot of these big ideas – like a complex conversation system – were excised early in the process because they really didn’t fit the game. Some were eliminated later because I wanted to, uh…  finish the game before I died of old age.  That kind of thing.

One concept that made it’s way into the final release that, in retrospect, I’m still not 100% sure about involved the fundamentals of the combat system – which in turn influenced the entire game system. This takes a little bit of explaining, but the short version is that I wanted to downplay the importance of levels, and increase the importance of numbers and teamwork. The idea here was to bring in a tiny amount of  “realism” – including some experiences I’d had with live medieval reenactment in my youth – as well as some influence from classic fantasy and science fiction stories. I can’t even remember the story (or the author), but I remember a scene from a Conan story or novel where he was cornered by several soldiers. One, two, maybe even three soldiers would not be too large of a problem for Conan. But when faced with… I think it was seven… with no way to escape he had no choice but to surrender.

In D&D, a high-level character like Conan would have no problem taking on a dozen 1st or 2nd level soldiers, even with a crappy armor class. Thanks to hit point scaling, and Conan’s high chance to hit (not to mention damage bonuses from feats / class abilities, in later editions), the soldiers couldn’t do enough damage to him fast enough before he’d taken them all out.  With some clever maneuvering, he could probably still escape with more than half of his hit points intact. This was worse in later editions of D&D than the more recent ones. Especially with the earliest editions, when “high level” was only around 6th or 8th level.  (Do you know how long it took me to realize that “mid-level” was around 10th in 3.0?)

I had a bunch of ideas for making an RPG more “realistic” (there’s that word again, gonna quit using it now) in this respect, and I still think they were great ideas for an RPG. But maybe they were not so great for a game with such deep roots in traditional RPGs (which were themselves deeply rooted in classic D&D game rules) like Frayed Knights.  I love the way they play, but it does feel a little “off” for a lot of players. Anyone who has played through Frayed Knights: The Skull of S’makh-Daon can tell you that many “boss battles” seem relatively trivial compared to fighting large numbers of enemies. This is also why most of the “bosses” in Frayed Knights: The Skull of S’makh-Daon are encountered with minions. Solo, even the toughest bosses can be relative pushovers.

At one point, it was even more extreme. Mid-way through development, I’d tweaked the rules a bit in the opposite direction, to give levels a bit more of a positive bias. Once upon a time, even at the highest levels, your party would be in serious trouble from an army of pus golems.

So what sort of things did I do to “flatten out” leveling for a more … I won’t say ‘realistic’ again in this context, let’s say ‘verisimilitudinous’  instead… experience?

1) I Flattened Out the Probability Curve:  Traditionally, differences in relative skill in RPGs follow a bell-curve. Near the center, when levels or skills are pretty evenly matched, you’ll get the majority of results. When you are throwing multiple dice – like an attacker’s roll versus a defender’s role, or rolling 3D6 for results – with some kind of additive or relative comparison – you’ll end up with something kind of bell-curve like. What this means is that within a relatively close window of values, you’ll have a very interesting fight, with plenty of possibilities for an underdog to get lucky, but still strongly favoring the stronger participant over successive rounds. But as those relative strengths diverge, the stronger competitor completely overwhelms the lesser. In Frayed Knights, I greatly flattened out the bell curve. So instead of this:

You get something more like this:

(I free-handed these graphs for illustrative purposes, so don’t try and read too much into them).

So an eight-point difference between being four points weaker than your opponent and four points higher than your opponent is still quite significant – a 32% chance of success versus a 68% chance of success! But the differences quickly flatten out beyond that. That same eight-point difference between being +16 higher than your opponent and +24 higher than your opponent is minor -  around a 92% chance of success versus a 95% chance.  The end result is that being overwhelmingly more powerful than your opponent doesn’t give you a linearly overwhelming advantage over your opponent. If it was down to a single probability check, if you had a 15 level advantage over your opponent, one in twelve would still defeat you.

While multiple cumulative die rolls means you don’t have to worry about insta-kills from trivial enemies, it does mean that against a sizable force, some hits are GOING to get through, and you can’t rely on level differences to protect you.

2) I reduced hit point scaling: In old-school D&D, a 3rd level character would have about three times the hit points – and thus be three times harder to kill – than her first-level counterpart. In Frayed Knights, increasing skill levels contributes a much smaller bonus to your base hit points.  I did the same thing with endurance as well. This mainly evened out the lower-level encounters. It also made balancing the effects and costs of spells (and enhancements) a serious pain in the butt.

3) Positioning of the enemies (and party) is important. Like most of these factors, I can’t claim this one is completely original – many first-person RPGs of the classic era that inspired Frayed Knights used an abstract positioning system that provided some protection to the rear ranks of monsters, as they are harder to get at. The trick, however, is effective positioning of the bad guys, as their numbers can work against them just as easily if the rear-rank opponents cannot use their best abilities against the party.  For planned encounters, this was easy to arrange, but the randomly generated encounters and patrols might occasionally be put together in a less-than-optimal fashion.

4) Combat is front-loaded. The “endurance” factor – a resource that must be expended in combat – means that characters will be more potent in the beginning of a fight than later (in a prolonged battled). In practice, since the monsters aren’t expected to survive more than a few turns anyway, this means the bad guys are at their best early in the fight – before the party has been able to whittle away at their numbers. There are a few exceptions, especially with groups with serious “buffing” characters in the ranks – but as there’s no point in the enemies holding anything back (unlike the party), a larger force means lots of incoming fire for the first couple of turns. I also included some position-dependent passive feats – like “Linebacker” – which provide more bonuses to an entire group (or in Linebacker’s case, the group behind the character with the feat).

5) Lots of party-enhancing spells and abilities. This mechanic wasn’t a deliberate attempt to enhance the threat of greater numbers, but it worked out that way. The end result is that many spells (which the monsters can use) act as a multiplier on the group’s combat abilities.  So while it’s probably not worthwhile for one guy to sacrifice an attack to buff himself, a group buff on a large group can be devastating if used early.

6) Lots of individual-crippling spells and abilities. My choice to put the “sleep” spell as an early spell choice really influenced this one.  What this came down to was that it’s really easy to use spells or magic items to keep one or two enemies on the ropes, unable to act effectively.  This makes facing only one or two opponents really easy.

7) Offensive group-based spells cost spell gems. This wasn’t always the case, either. But perhaps because all of these other factors made groups of enemies so potent, a spell that affects groups of enemies was correspondingly powerful as well.  Too powerful, without making it cost an additional resource.

8) I refused to make the bosses cheat.  Mostly. One of the things that drives me crazy about some RPGs – especially JRPGs – is that the boss monsters are often virtually or totally immune to major debilitating spells (like the kind I mentioned in point 6). Blindness? Silence? Sleep? Fuggedaboutit. There’s no explanation – they are simply immune to most clever tricks because they are supposed to be awesome and challenging. I took the more traditional western RPG approach to the big bads, which means that concentrated fire can disable or destroy them without much more effort than any other opponent.

9) Decent teamwork AI. This one is actually pretty funny. I made the mistake of doing a lot of the enemy balancing when the AI was effectively acting at random every turn.  This caused unsurprisingly inconsistent results. An encounter might be trivial four times out of five, but devastating on the fifth try, as the enemies used their abilities in something resembling a strategy. Not wasting a turn healing an unwounded companion, for example. Once I started giving the AI something resembling brains, however, things turned nasty quickly.  The enemies became frustratingly nasty with very little logic and tactics. For a strategy or war game, they’d be great, but for an RPG, they were not much fun. They’d pull the same kind of tactics that would serve a player – focus on suppressing the spellcasters, and whittling down the party numbers by concentrating fire on one player character at a time. It was very difficult to finish a combat against some enemies without at least one party member incapacitated. And this was with the AI still doing some really stupid moves a lot of the time!

So I actually had to tone down the AI and make them more “dramatically responsible” rather trying their best to beat or cripple the player’s party. Yet even that wasn’t good enough, and I had to tone them down more. One tester completed the game on one of the intermediate builds where the AI was only somewhat toned down from its most-brutal level (and still making more stupid mistakes than they do now…) I have to give him credit – even *I* did not try to play through the whole game at that punishing level. Anyway, the AI was further gimped to use their “Brains” score to make decisions, to be “more random” (again) in their choices, and to more heavily weight actions that would challenge the player rather than just send them back to the inn to restore incapacitated party members.  So, for example, they’ll now prefer to hurt an uninjured party member than finish off a wounded one.

But while the AI is far from perfect, they do apply some tactics to enhance each other’s fighting ability, to form something resembling teamwork. Sometimes. :)

Results:

Although I made some later changes to tilt the balance a little more back in the traditional direction, as it stands Frayed Knights: The Skull of S’makh-Daon has a different flavor of combat from most other RPGs of its style.  In recognition of this, the game  even awards an experience point bonus for facing larger groups – so facing six goblin Whitelisted Mages as a group is worth more experience points than six far-easier battles against them one at a time.

I personally think it’s cool. But was it the right game for this approach? That’s the debate I’m facing in development of the sequel. Should the balance be tilted further in the traditional direction? Now would be the time to do that… On the one hand, if I were to do it all over again, I’d definitely skew a few of these factors back in the traditional direction, and make trivial enemies more trivial and boss encounters more — uh, bossy. But on the other hand, I am working on a sequel, which should be faithful to the experience of the original.

    I think the combat system is mostly fine as it is. Groups of enemies within about 3 levels of the party are either challenging or at least pretty quickly wear down endurance.

    Groups of enemies 5 levels lower aren’t that threatening. They miss most of the time and fighting them can be either tedious or just expensive, if I waste spell stones at them, instead of just pressing ‘A’ repeatedly and using Life Tickle / Flow when someone gets hurt. Farming drama stars this way still wears down my endurance eventually.

    Well, groups of hobgoblin officers are still tough nuts even at level 13, but no longer outright deadly. I complained about them, but in retrospect hobgoblins are supposed to be a pretty well organised race and throw a well-coordinated defence. Which they do in FK.

    Bosses would be way more scary if they had more minions. Something a few levels higher than the party, but alone, goes down quickly. Give it 2-3 minions and it is much tougher. 4-5 minions and it gets scary. It also makes sense for bosses from intelligent races to have “elite guard” with them and not be able to take on entire armies on their own.

    I think the game could use difficulty levels, which would mostly affect the AI.

    Higher level spells or just uber versions of lower level spells cost a lot of endurance. It may stop scaling well at some point. I often end up using low level spells because they are more endurance efficient.

    So well, your way is a bit unorthodox, but keep it up.

  • Greg said,

    I think getting rid of 7, and going easy on endurance loss (4), would go a long way. I don’t think people do not want challenging fights, but they do want to be able to go into a dungeon and not worry about a ton of consumables. I think your audience who like to hoard or not need consumables would be happy.

  • GhanBuriGhan said,

    I didn’t have many complaints about the combat. It was hard, but in a good way. It would be nice to have an alternative to going back to town for a full heal, it was a bit too much backtracking for my liking from some of the more remote areas.
    That numbers matter was not something I disliked. If you run into a large group with spellcasters, you knew you were in trouble. If anything, I think you can decrease the number of spells somewhat (eliminating some fairly redundant choices) while adding more active melee combat feats, to make the melee characters more intersting to play.

  • Robyrt said,

    If you want to make bosses more “bossy” without changing the combat math, you could write your story in such a way that more bosses are part of a pair or group. Demon’s/Dark Souls does this to great effect without using 2x the development resources: an existing easy boss is made scary by dropping in a second copy once the first reaches 30% health, or adding mooks with annoying abilities, or whatnot.

    The infamous “Four Kings” fight is actually just a room that spawns copies of the same boss on a timer, and a victory condition that triggers when you’ve killed 4 of them. The boss has much better attacks from far away, so the player has an incentive to run around frantically, creating a great vibe of desperation even if the player is winning handily.

  • Daniel King said,

    Well it’s been almost a year since I completed this now, so I’m getting hazy, I recall really enjoying it though, so I’m sure I’ll be happy with whatever tweaks you deem appropriate. :-)

    Bring it on!

  • Baudolino05 said,

    I think Robyrt is right,Jay: you can easily enhance the challenge of the boss fights without change ruleset. You just need to design them in a different way, something like a puzzle to solve (look Zelda for inspiration :D).

  • Eric said,

    I think that combat in Frayed Knights was a high point of the game, and was balanced very effectively. I definitely think your efforts to make larger groups of enemies more threatening pay off, and I could rarely just turn on auto-pilot when fighting unless the enemies really were just pipsqueaks.

    There is a downside, though – when you make the majority of fights significantly challenging, it doesn’t feel as if you’re making progress in the game quite as quickly. I found that even though I’d come up with some masterful strategies, sometimes I’d get into fights where four out of five times, I’d get completely wiped just because the enemies happened to, say, have a party-affecting spell and decided to spam it, and there was nothing I could do but get lucky.

    The sweet spot of everything, I think, is to have combat that isn’t necessarily difficult to get through alive, but that has strong disincentive for simply mashing the attack button to get through. I think parts of Frayed Knights did this very well, and the endurance mechanic helped this immensely, as it encouraged long-term efficiency.

    To improve things further, I’d like to see more enemies that require specific strategies to take down. More potent resistances and immunities, more enemies with defenses like magic shields (say, immortal until minions are dead), that kind of stuff. By having mixed encounter groups against enemies requiring varied solutions, combat can remain interesting and engaging without necessarily just being frustratingly hard.

  • Rampant Coyote said,

    I’m glad you said that, Eric. That’s one focus I’m trying to put into FK2. I kinda realized it at the end of FK1 and tried to retro-fit more of that element in there, more deliberately, but there wasn’t enough time to do a thorough job of it.

    However, I don’t want to get into a pure rock-paper-scissors situation where there’s always a “best” solution. I do want to keep it a bit more open-ended than that. But I want to lean a bit more on the side of giving monsters very specific advantages and disadvantages to force the player to “mix up” their strategies a bit more.
